137032600 âFrigidaire washer Dryerâ Thermal⣠Limiter is a temperature-sensing safety device designed for⢠Frigidaire washer-dryer âcombinations; it functions âas a thermal cutoff/limiter that interrupts heater power when appliance temperatures exceed a predefined safe threshold. The limiter is a passive protective component â˘- commonly âa one-time thermal cutoff or a fixed-temperature limiter – that is installed close to the âdryer heating assembly to provide a final level of over-temperature protection independent of the control electronics.
Inside the⣠appliance the thermal limiter âis typically wired in series with the dryer heating element circuit or âthe heater ârelay on the control âboard and interacts directly with the heating âsubsystem, air delivery/venting pathwaysand the appliance’s control logic. When temperatures rise beyond the component’s rating âdue to heater faults, â˘restricted airflow, failed cycling thermostatsor other faults, the limiter opens and removes power to the heater to âprevent excessive case temperatures⤠and reduce fire risk; conversely, a failed-open limiterâ will prevent the dryer from⣠producing âŁheat. Technicians⣠will frequently encounter the limiter when diagnosing no-heat conditions, overheating⣠eventsor as partâ of routine safety inspections of the heating circuit.
In this article you âwill âfind⣠a focused technical overview âof the part’s âfunction and typical installation⣠locations, guidance on compatibility and⢠how to identify âthe âcorrect replacement, common failureâ symptoms and diagnostic checks (including continuity testing and visual inspection)and practical replacement considerations such as temperature rating, âŁmounting orientation, wiringâ connectionsand the importance of addressing root causes like airflow restriction before replacing the limiter. Safety andâ basic âservice precautions, including disconnecting mains power and verifying âcomponent ratings, are also âcovered to assist technicians, engineersand informed applianceâ owners in making informed repair decisions.

Function and Role of the Thermal Limiterâ in WashâDryâ Cycle overheat Protection
The 137032600 Frigidaire Washer â¤Dryer Thermal Limiter is a temperatureâsensitive safety device mounted in the heater assembly âthat interruptsâ the â¤heater supply when cabinet âor airflow temperatures exceed a⤠defined âthreshold.⣠Designed to protect against sustained âovertemperature during combined washâandâdry cycles,the limiter âfunctions as the last line of defense after control thermostats and electronic limiters: when it opens it⢠removes power from the heating element or its âŁrelay coil,preventing further rise in air temperature âand potential componentâ damage. In practical operation, a limiter will â¤present low resistance (closed) at ambient temperatureâ and become an⢠open circuit when its rated trip temperature is reached; some limiters are nonâresettable thermal cutouts while others are autoâresetting thermal switches, so confirming the exact specification for the 137032600 unit on the parts âsheet is necessary before repair or replacement.
- Primary behaviors: normally closed at ambient,opens at trip temperature to interrupt heater circuit.
- Common symptoms of a tripped âor failed limiter: â˘dryer sectionâ produces no heat, continuity â˘absent at room temperatureor visible heat damage at the âmounting area.
- Troubleshootingâ steps: verify continuity with an âohmmeter at ambient,⤠inspect the limiter mounting and âŁnearbyâ airflow path for lint/obstructionand replace âwith the identical part â¤number â¤if the limiter is open or shows thermal damage.
| Item | Description |
|---|---|
| Function | Interruptsâ heater⤠supply when measured temperature exceeds manufacturerâspecified limit to prevent overheating. |
| Behavior at ambient | Normally closed (low ohms); trips⣠to open (infinite⣠resistance) at âŁthe rated temperature. |
| Service note | Replace with the same part number and mounting orientation; verify whether⢠the device is oneâtime thermal cutout or an autoâreset switch âfrom technical documentation. |
When diagnosing an overheat shutdown during the washâdry sequence, technicians should â˘consider theâ limiter in the⣠same workflow as â˘thermostats, heater relaysand airflow inspections as its operation is dependentâ on âboth temperature and proper airflow/cooling. For example, a failing blower or blocked lint filter can raise local temperaturesâ enough to trip the limiterâ even though the⣠control and heater element are functioning normally; conversely, a stuck heater relay âcan cause continuous heating that the limiter is intended to stop. alwaysâ confirm the 137032600 Frigidaire Washer Dryer Thermal Limiter’s exact ârole (oneâshot vs. resettable), mounting locationand electrical continuity before declaring unrelated components as the root cause.
How the 137032600 Frigidaire Washer Dryer Thermal Limiter Operates Within the Heater and Control Circuits
The 137032600 âFrigidaire Washer Dryer Thermal Limiter is a temperature-actuatedâ protective⢠device that interrupts the heater circuit when local temperatures exceed âits set threshold. Installed in series with the heatingâ element and frequently âenoughâ tied into the control board’s safety input, the limiter is normally closed during normal operationâ and âopens at⤠over-temperature to remove âpower from the â˘heater and, in many designs, to⢠signal the controller to âinhibit drying cycles. Technically,the limiter senses air-path â˘temperature at the heater or blower housing and provides a fail-safe against sustained overheating caused by airflow restriction,aâ shorted heating element,or control circuit⣠faults.
- Common symptoms: no âheat while the drum and motor⤠run, intermittent heatingor repeated trips after a short run.
- Electrical role: wired in series âwith the heater element and as a safety input to the control board.
- Replacement compatibility: match temperature rating, connector typeand mounting location to avoid false trips.
| Item | description |
|---|---|
| Function | Interrupts heater and safety circuits when measured temperature exceeds the cut-out point. |
| Mounting | Typically on the heater housing or blower outlet to sense exhaust/air-path temperature. |
| Reset behavior | Either a one-time thermal fuse (replace after opening) or a â¤bi-metal cutout (resets after cooling); âŁverify type before repair. |
For troubleshooting and repairs, verify continuity with a multimeter when theâ unit is cold and inspect for âsigns of overheating or damaged connectors; an open limiter generally indicates an⢠over-temperature event â¤rather than a failed âcontrol board. When replacing the limiter, select a part that matches the original’s temperature rating, electrical configurationand mounting orientation to â¤maintainâ correct thermal response. In practice,resolving theâ root cause (blocked venting,lint buildup,or faulty heater element) is necessary after replacing the limiter to prevent recurrence âof trips âand to restore safe operation.
Common Failure Symptoms and Electrical/Temperature Signatures Indicative of Thermal Limiter â¤Fault
The 137032600 Frigidaire Washer Dryerâ Thermal Limiter is âa temperature-actuated protective âdevice placed in the heater circuit to interrupt power if the heater or surrounding area exceedsâ a⢠safe âtemperature. â˘In normal operation the limiter presents a low-resistance pathâ (closed) and allows the heater or motor circuit âŁto âŁbe energized;⢠when the limiter reaches its specified trip temperature it opens and becomes an electrical âbreak, preventing âfurther âŁheating. This part is⤠intended as an OEM-style⣠replacement for compatible Frigidaire washerâdryer assemblies, but â˘correct fit and connector type should be verified against the appliance model and part cross-reference before installation.Mechanically it is indeed mounted close to the heater âor ductwork to âŁsense actual operating temperature and is expected to fail open rather than shorted when itâ reaches end-of-life or sees an overtemperature event.
- Complete loss of heat while the motor and controls operate normally.
- Intermittent heating or cyclesâ that stop heating after a short run time.
- line-voltage present on the heaterâ feed but absent downstream of the âlimiter (indicates an âopen limiter).
- Burnt connector, discolored housingor evidence of⢠overheating⢠near the limiter.
| Item | Description |
|---|---|
| Normal electrical reading | Continuity or very low⤠resistance âat ambient temperature (closed). |
| Fault electrical reading | Open circuit (infinite resistance / OL) across the limiter whenâ cold if the limiter has tripped or failed. |
| In-circuit voltage⣠signature | Lineâ voltage present on the supply side and none âon the load âside when the limiter is open; no voltage âdrop⤠when closed. |
| Temperatureâ behavior | Opens at⣠the â¤specified trip temperature to interrupt heater power; some limiters are non-resetting one-shot devices while âothers may be resettable-check the part specification. |
For troubleshooting, confirm mains power is removed, â˘then measureâ continuity across the limiter at ambient; a reliable thermal limiter will show low resistance when intact and a⣠clear⢠open whenâ blown. While the appliance is powered and operating a two-point voltage check can distinguish an open limiter from other failures: if voltage appears at⤠the supply terminal but not at the heaterâ terminal,â the limiter has opened under load. repeated or âpremature limiter openings usually indicate⢠an upstream fault such as restricted airflow, failed heater âŁelementor blocked vents rather than a defective limiter âitself; address those causes before replacement.Replace with a like-for-like⤠component that matches the thermal trip rating,⤠mountingand connector â¤styleand always⤠verify theâ replacement against the appliance âmodel and wiring diagram.
Replacement Considerations,⣠Installation Procedure âŁand PostâReplacement Verification for the⣠Thermal Limiter
The 137032600 Frigidaire Washer Dryer Thermal Limiter functions as â˘a temperatureâsafety device â¤in the dryer/heater circuit: under âŁnormal operating conditions it provides âa closed path for the heater relay or âelement controller andâ opens âŁwhenâ temperature exceeds its designed trip point âto prevent overheating.Whenâ selecting⣠a replacement, confirm electrical and mechanicalâ compatibility – matching trip temperature, mounting footprintand terminal style (spade vs. pigtail) is required to preserve control logic and thermalâ protection.⤠Technicians should verify whether the limiter is a oneâtime thermal cutoff âŁor a⣠resettable thermostat by âconsulting the service literature for the exact⤠part number; âinstalling â¤a limiter with a different trip characteristic âŁcan create nuisance shutdowns⢠or unsafe operating temperatures for the heater and drum components.
- Isolate power and remove access panels before handling the limiter.
- Document connector positions and take photos to ensure correct reassembly.
- Check ambient â˘continuity with a multimeter (expect nearâzero ohms if closed) â¤to confirm failureâ before replacement.
- Install the replacement with identical terminal types andâ secure mounting to maintain sensor contact and heat transfer.
- After replacement, perform an operational heat cycle while monitoring temperature and controller behavior to confirm proper reset/cutout and absence of overheating.
Installation procedureâ notes: remove panels to access the heater box or controlâ assembly, disconnect the limiter leadsand transfer the limiter into the original mounting bracket so that thermal coupling to⤠the heater or air duct isâ preserved; use crimped OEMâstyle spade connectors or âŁheatâshrinked soldered joints where appropriate to preserve insulation and strain relief. For postâreplacement verification,⢠measure continuity at⣠ambient, run a diagnostic heat cycle and monitor âwith an infrared thermometer at the outlet or across the heater to verify⤠expected⣠temperature rise and that âthe limiter opens only at its specified threshold; confirm the control completes the normal heat cycle andâ the âŁblower/venting remain unobstructed. Record the part number and test results in the service log to ensure traceability and âto assist withâ future troubleshooting.
| Item | Description |
|---|---|
| Trip characteristic | Specified by part/service⤠literature; match âthe original limiter to maintain safety and âŁcontrol timing |
| Connector type | OEMâ spade or pigtail – use identical connectors for reliable contact |
| Continuity (ambient) | Limiterâ should âshow continuity when cold; open circuitâ indicates a blown limiter |
Q&A
What is Frigidaire part 137032600 and what doesâ a thermal limiter do?
Part 137032600â is a thermal limiter (thermal cutoff/thermal fuse) used on some Frigidaire⣠washer-dryer/dryer models. Its job is to â¤protect the heating circuit from⣠overheating by opening (cutting electrical continuity) when the temperature exceeds a safe limit. That⤠prevents fires and damage to internal âcomponents.
What symptomsâ indicate the â137032600 thermal limiter âŁhas failed?
Common symptoms âŁinclude: the dryer runs but produces no heat, theâ dryer stops heating intermittentlyor in some wiring configurations the dryer may stop running wholeâ cycles. You may also notice strong heat buildup, repeated cycling offor error codes related to heating/temperature on models with diagnostics.
Is the â137032600 thermal âŁlimiter resettable?
Most thermal âŁlimiters/thermal cutoffs of this type â¤are non-resettable one-time devices. Once they open from an overtemperature event they must be â˘replaced. Some appliances âuse resettable âŁthermostats, butâ you should not assume the limiter is resettable – check âthe service manual or the part itself.
How can I test the 137032600 âthermal limiter?
Always disconnect âŁpower before testing.â Remove the limiter from the appliance or âat least disconnect⤠its leads.
